Sacroiliitis identified by MRI is considered as a keystone in the diagnosis of spondyloarthritis. To reduce the number of unnecessary MRI scans it would be ideal if sacroiliac (SI) joint pain provocation tests could be used to identify patients at risk of having sacroiliitis. The aim of the current study was to investigate the diagnostic value of three pain provocation SI-joint tests for sacroiliitis identified by MRI. Patients (n=454, mean age 32 years, 54% women) without clinical signs of nerve root compression were selected from a cohort consisting of patients with persistent low back pain referred to an outpatient spine clinic. Data from the Gaenslen's Test, Thigh Thrust Test and Long Dorsal Sacroiliac Ligaments Test and sacroiliitis identified by MRI were analysed.Purpose and background:
Methods:
The outcome of studies on back pain is usually measured at specific intervals (1 month, 3 months, etc.) However, because LBP is a recurring condition it would be more relevant to identify outcome in relation to course over time. A new data collection tool was recently developed (SMS-Track), allowing this to be done.
present the SMS-Track system give some examples of how the course pattern varies between patients with back pain.Background
